What are the forces acting on the plane in flight?

An airplane in flight and moving straight is subject to forces such as gravity, thrust, and aerodynamic force. In a curvilinear motion, an inertial force is added to these forces.

Aerodynamic and thrust forces are superficial, that is, not related to the mass of the aircraft. Gravity and inertial force are related to the mass of the aircraft and must be overcome in order to fly.
